The antinucleon-nucleon quasi-bound states: J/psi and atomic evidence
S. Wycech, B. Loiseau
The measurements of J/psi decays into photon, proton and antiproton show a strong enhancement at the proton-antiproton threshold not seen in the decays into neutral pion, proton an…

On the nuclear states of K^- mesons
S. Wycech, A. M. Green
The KNNN bound states recently discovered at KEK are studied. It is shown that the Lambda(1405) and Sigma(1385) resonant states coupled to the KN system may generate an attraction…

The Interest in Kaonic-Deuterium Atoms
S. Wycech
K meson-deuteron scattering lengths, atomic level shifts and widths are calculated. These quantities depend on controversial kaon-nucleon scattering amplitudes extrapolated by few…
